Answer:
104 degrees
Step-by-step explanation:
90 + 54 + 132 = 276
360 - 276 = 104
Answer:
HJ = 52
JK = 79
Step-by-step explanation:
Hello, I want to assume you are trying to determine either HJ or JK. Below is an illustration of how to determine either HJ or JK.
From the question given above, the following data were obtained:
HJ = 5x – 3
JK = 8x – 9
KH = 131
If we draw a straight line, we'll observe the following:
H_______J_______K
KH = HJ + JK
Next, we shall determine the value of x.
HJ = 5x – 3
JK = 8x – 9
KH = 131
KH = HJ + JK
131 = (5x – 3) + (8x – 9)
131 = 5x – 3 + 8x – 9
Collect like terms
131 + 3 + 9 = 5x + 8x
143 = 13x
Divide both side by 13
x = 143 / 13
x = 11
Finally, we shall determine HJ and JK. This can be obtained as follow:
For HJ:
HJ = 5x – 3
x = 11
HJ = 5(11) – 3
HJ = 55 – 3
HJ = 52
For JK:
JK = 8x – 9
x = 11
JK = 8x – 9
JK = 8(11) – 9
JK = 88 – 9
JK = 79
Answer:

Step-by-step explanation:
<u>Area of a rectangle</u>
A rectangle of width W and length L has an area of:
A = W.L
The given rectangle has a length of L=10 inches and a width of W=8 inches, thus its area is:
A = 8*10 = 80

If each corner is cut by a square of x*x, then the total area will be:

The new area is
square inches
2x+7=3
move 7 to the other side
sign changes from +7 to -7
2x+7-7= 3-7
2x= 3-7
2x= -4
divide both sides by 2 to get x by itself
2x/2= -4/2
answer:
x= -2

Hello! Sorry about your luck before although im 99% sure my answer is correct.
Answer: area is 180
Step-by-step explanation:
Ok so first starting off im going to calculate the area for each shape serperately and add them up since thats easier so as demonstrated in the picture the rectangle is 25 because i multiply by base × height and the base and height is 5 and 5 pointed in the picture so thats 25 although i didnt calculate the rest because the base and height is the same for each so we can just do 25 × 6 to get all the rectangles so 25 × 6 = 150 now we got the easy part out of the way now we should do the triangles I pointed to the base and height for that on the left the base being 5 and the height being 3 5 × 3 = 15 BUT WAIT this isn't are area for the triangles because when finding area for triangles we have to divide by 2 so... 15 ÷ 2 = 7.5 since there are 4 of those triangles I dont have to solve for the rest because i can just do 7.5 × 4 so...
7.5 × 4 = 30 now we just combine those areas together! so... 150 + 30 = 180 so 180 is our area HOPE THAT HELPS!
